zero_dte_volume_share

Share of the session's option volume in contracts expiring that session, denominator truncated at 120 DTE. ONLY SPY, QQQ AND IWM, which list a 0DTE expiry every session; NULL for every other name, whose Friday weekly would make it a once-a-week statistic under the same name.

Provenance

Source: core.option_strikes
Cadence: daily, XNYS sessions; fetched 19:00 ET, first materialised by the next run
Read by: Page 4's 0DTE share of volume (DATA_SOURCES.md), a header cell for SPY, QQQ and IWM
Point-in-time: RESTATED — values change as corporate actions arrive. Each row's vintage_ts records when it was computed.
Export restriction: INHERITED FROM core.option_strikes, whose uw_option_chains SourceSpec records the basis: UW API Basic is a personal-use tier and the rows carry OPRA-derived NBBO and greeks (DESIGN.md §9.15, ADR-0014). A statistic computed from restricted data is still restricted - a sum is not a licence.
